A sling across the bay

摘要

As I drive out onto San Francisco Bay's new bridge, an empty five-lane freeway curves towards me. In the distance I catch sight of the structure's architectural signature: a single suspension tower, 160 metres high. When finished, cables will arc down from the tower's perch and hold the roadway aloft. At almost 400 metres long it will be the largest self-anchored suspension bridge ever built - a beautiful structure worthy of comparison to the nearby Golden Gate Bridge.
